Boxing and martial arts have become popular ways to get in shape for both men and women. No opponent is needed to get results -- the punching motions and footwork can improve your cardiovascular endurance and muscle strength. Boxing basics, plus more advanced moves, are covered in "Start Punching," a video by kickboxing champion Derek Panza.
"Start Punching": The formidable-looking Panza is a former kickboxing and karate champion. But don't let the bald head, bulging biceps and stern gaze intimidate you -- he's a skilled teacher who patiently takes viewers through a thorough and demanding workout that includes stretches, warm-ups and punching technique. Panza is a stickler for proper form when throwing uppercuts, jabs and hooks.
